Ranked in these QuestionsQuestion Ranking
Pros
Pro Good at creating complex visual effects and filters
Pro Fast rendering of complex scenes
Because Processing doesn't keep track of shape objects it's more efficient than other libraries. Processing can do more complicated effects faster than other libraries. Although this means you have to keep track of more yourself in your code, it also means you have more control over the finer details of how things are rendered.
Pro Cross-platform compatibility
In processing you can write code in both JavaScript and Processing code. This allows you to use existing Processing code on the client side.
Processing code is similar to Java in that it has static typing. This can make more complex calculations more robust, and less likely to cause conflicts.
The library takes a more frame based approach to rendering, so you use drawing functions to draw directly to the frame without objects. This can make it easier to write efficient full frame rendering scenes and post processing effects.
Pro Many chart types available
There are more than 20 types of charts available for use.
Pro Wrappers for ASP.NET, ASP.NET MVC and Apache Wicket
Each chart can be implemented to ASP.NET and ASP.NET MVC applications, with detailed documentation and guides for each.
Pro Good documentation
Each of the available charts has documentation and guides available for every different implementation (JavaScript, ASP.NET etc.)
Pro Interactive charts
The charting widget is built to facilitate client side interactions and notifications.
Pro Out of the box pan-and-zoom
Zoom-in on specific points of interest on the graph with the mouse – a single property allows this out-of-the-box.
Pro Supports combining different charts
You can combine different charts (they can be of the same type or even different types of charts) to display data correlations.
